Rare Event Searches ToolKit for Physics

A process to include detector energy resolution in a TRestDetectorHitsEvent.
TRestDetectorHitsSmearingProcess will introduce a stochastic smearing on the energy of the hits for each event. The total energy of each event will be re-distributed following a gaussian shaped function.
The energy resolution will follow a root square law with the energy using the energyReference
and the resolutionReference
as a pivoting point.
Therefore, the process defines only two parameters, one being the energy at wich the energy resolution is "known", and the FWHM in percentage at that given energy, resolutionReference
.
The following image is the result of smearing the energy of an electron gun of 250keV. It was produced using the exercise 3.2 inside the day3/session2 at the rest-school repository.
